I won't get into how I got in this position but the wires are disconnected from the sensor. I have a blue which is a double wide and appears to be a ground,and a green, white and red. Can anyone tell me which goes where. This is unit 8330B633. There are 6 pins for quick connects labeled FREEZE B- Y GH and GR I am not certain on the R It also says
1976-38 (2-03) P.P. Any help would be fantastic. I'm melting here

R is 12VDC+ (Red)
B is 12VDC- (Blue)
Y is for the A/C Compressor (Yellow)
GH is for A/C Fan Hi Speed (Green)
GL is for A/C Fan Lo Speed (Grey)
W is for Furnace (White)


Is it time for your medication or mine?

Your unit pin out is here (page 4).

You can know the functions at the A/C unit based upon that and likewise the ones on the thermostat by looking it up. What you can’t tell is what color the RV builder used for what function. So what you need to do is take the thermostat off the wall without disconnecting anything. Then you can match the functions as Old-Biscuit described above. The thermostat should have similar or the same labels as the unit. B,Y,GL,GH are the 4 you are looking for.

Well the circuit board did not give me the answer but you got me in the right direction. By pulling the wires out of the wall I could see what each wire was connected to. Yellow is my red and grey is my white. Problem solved. Thank you very much

For me, I normally take a picture of the wire connections before removing. But every now and then I forget [emoticon]

Use colored ty-wraps to mark each wire, makes it real easy to know what wire goes where.

Not even close to industry

Yellow and White are mainly used as GROUNDS

Some real rookie floor jockey was put on pulling wires.....
"Which wires do I run Boss?"

"See that rack over there....it has spools of colored wires"
"OK Boss"
